Second base prospect Jedd Gyorko hit a grand slam off Hector Noesi in a six-run first inning, and the San Diego Padres rolled to a 9-3 win over the Seattle Mariners on Friday in the spring training opener for both teams.

In a game that marked the 20th anniversary of the Peoria Sports Complex, the shared home of both clubs, Chris Denorfia singled had a go-ahead RBI single in the first following an error by new Mariners left fielder Raul Ibanez. Noesi forced in a run with a bases-loaded to Will Venable, his 11th batter, and departed after 42 pitches.

Noesi, the loser, allowed six runs — four earned — four hits and four walks while retiring just two batters.
